Use of static magnetic fields to increase CO biofixation by the microalga Chlorella fusca. | LitMetric
This study aimed to use different conditions of magnetic field (MF) application during Chlorella fusca cultivation and evaluate CO biofixation by the microalga through growth kinetics in addition to the biomass composition. For this purpose, we tested different MF intensities applied for 1 h d and for 24 h. Cultures exposed to the MF for 1 h d (in both intensities) had greater biomass concentrations (1.42 g L) and 34% more productivity in the same time as the control assay. The biofixation rate increased by 50% with 60 mT for 1 h d, and the protein content was enhanced by 30 mT (56.21% w w). This study was the first to consider the MF effect on CO biofixation. MF applied for 1 h d proved to be an efficient alternative method to increase the CO biofixation and growth of C. fusca besides to be an inexpensive and nontoxic method.
